In DNA, which bases hydrogen bond?
A-T; G-C
In DNA, the bases that hydrogen bond are the nitrogenous bases. There are four nitrogenous bases found in DNA: adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair up with each other in a specific way: A can only bond with T and G can only bond with C. These specific pairings of nitrogenous bases are known as base complementarity.
The hydrogen bonding occurs between the nitrogen atoms of the base pairs, which are located in the center of the double helix structure of DNA. Specifically, A nucleotide pairs with T nucleotide through two hydrogen bonds, while G nucleotide forms three hydrogen bonds with C nucleotide. These hydrogen bonds are essential for the stability of the DNA molecule and help to maintain the proper structure of the double helix.
